When Eritrea gained independence in 1993, Ethiopia suddenly found itself without a coastline and so it took the logical step of disbanding its navy. Now, it is reconsidering its decision and its latest manoeuvres in the region suggest it could be shopping around its neighbourhood to find a naval base it can use.

Prime Minister Abiy Ahmed recently said on state TV: “We built one of the strongest ground and air force in Africa… we should build our naval force capacity in the future.”
His comments revealed the country’s naval ambitions but his plans for how to achieve this goal have not been made public. However, Ethiopia’s latest push to enter into deals with its coastal neighbours signal something is afoot.

Misplaced priority for couple of reasons.

1. For lack of coastline, a Navy will only serve the purpose of offence and not defence.

2. Waste of scarce resources, why maintain a NAVY you don't need,when you already have an army and air force that you truly need.

3. add yours
